Has anyone put a 80's 8.5 in their older Pontiac.
It looks like the overall width dimension on the 8.5 are 3" shorter and the shock holes are 2"...

Hi, hoping someone can help me. I have a 71 GTO convertible which I have had for 20 years. About 15 years ago I purchased a THM 400 automatic transmission with a switch-pitch stall designed for high performance. At the time I intended to drag race the car but never did. It is just a...
